Paul, brother of presenter Jonathan Ross, said the financial stresses from being landed with a huge tax bill meant he was in need of an "escape", while he and his wife didn't have sex for a year.

The first time he met his gay lover, a former English teacher, at the dogging spot he ended up having sex with him in the bushes. They then went on to have a year-long affair meeting regularly at his lover's flat before he started his daily breakfast show, he says.

He also told the newspaper that he's undergoing counselling for drugs after he became hooked on mephedrone or meow meow, introduced to him by his lover, which he says he was snorting up to six times a day during the affair.

A picture, obtained by The Sun on Sunday, even shows the father snorting the substance off his lover's face.

"It was a dependency that got worse and worse - and I was then doing five or six lines of it," he says.

Despite the affair his wife of ten years Jackie, who eventually discovered what was going on when she tracked her husband's phone using the Find My iPhone app after she grew suspicious, says she's sticking by him.

"It was all about the drugs," Paul continues.

"I have started counselling for my drug addiction. I have had two sessions already. I can’t believe how stupid I’ve been."

While Denise says: “I know 90 per cent of Paul is a good man. He’s a good dad. I feel the sex was part of the mephedrone package, I don’t see it as a gay relationship, I see it as part of the drugs."
